Beyonce is known to hide her personal life from the public, but in her upcoming HBO documentary, Life is But a Dream, the sensational diva is revealing everything — including her speculated miscarriage!!

Say whaaaat?!?

Before getting pregnant with Blue Ivy, Bey apparently experienced a loss that made her write "the saddest song" of her life.

But that wasn't the first instance that pointed at her miscarriage. Her hubby, Jay-Z initially revealed the mishap by writing the song, Glory.

The lyrics read:

"Last time the miscarriage was so tragic/We was afraid you’d disappear/But nah baby you magic."

That's deep!

And since the cat has been pretty much out of the bag, Miz Knowles wants everyone to know the truth, and you will be able to know errrything in her highly anticipated and self-directed movie on February 16.
